System object: dsp.ZeroCrossingDetector
Package: dsp

Count zero crossings in input

Syntax

Y = step(H,X)

Description

Y = step(H,X) counts the number of zero crossings, Y, in the vector or matrix input X.

    Note:   H specifies the System object™ on which to run this step method.

    The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
